| Special Charges                | SPECIAL CHARGESThe Company recognizes certain transactions and events as special charges in its consolidated financial statements. These charges (such as restructuring charges, impairment charges and certain settlement or litigation charges) result from facts and circumstances that vary in frequency and impact on the Company's results of operations. In order to enhance segment comparability and reflect management's focus on the ongoing operations of the Company, special charges are not reflected in the individual reportable segments operating results.2012 Business Realignment Plan During 2012, the Company incurred charges of $185 million resulting from the realignment of its product divisions into two new operating divisions: the Implantable Electronic Systems Division (combining its legacy Cardiac Rhythm Management and Neuromodulation product divisions) and the Cardiovascular and Ablation Technologies Division (combining its legacy Cardiovascular and Atrial Fibrillation product divisions). In addition, the Company centralized certain support functions, including information technology, human resources, legal, business development and certain marketing functions. The organizational changes are part of a comprehensive plan to accelerate the Company's growth, reduce costs, leverage economies of scale and increase investment in product development. In connection with the realignment, the Company recognized $109 million of severance costs and other termination benefits after management determined that such severance and benefit costs were probable and estimable, in accordance with ASC Topic 712, Nonretirement Postemployment Benefits. The 2012 business realignment plan reduced the Company's workforce by approximately 5%. The Company also recognized $17 million of inventory write-offs associated with discontinued CATD product lines and $41 million of accelerated depreciation charges and fixed asset write-offs, primarily associated with information technology assets no longer expected to be utilized or with a limited remaining useful life. Additionally, the Company recognized $18 million of other restructuring costs, which included $7 million of contract termination costs and $11 million of other costs. During the first quarter of 2013, the Company incurred $34 million of additional special charges associated with the 2012 business realignment plan. Of the $34 million in additional special charges, the Company recognized $10 million of severance and other termination benefits after management determined that such costs were probable and estimable. The Company also recognized $18 million of inventory write-offs associated with discontinued CATD product lines, $2 million of fixed asset write-offs and $4 million of other restructuring costs, all as part of the Company's continued integration efforts.A summary of the activity related to the 2012 business realignment plan accrual is as follows (in millions): EmployeeTerminationCosts InventoryCharges FixedAssetCharges Other Restructuring Costs TotalBalance at December 31, 2011$— $— $— $— $—Cost of sales special charges5 17 — 2 24Special charges104 — 41 16 161Non-cash charges used— (17) (41) (3) (61)Cash payments(52) — — (7) (59)Foreign exchange rate impact1 — — — 1Balance at December 29, 201258 — — 8 66Cost of sales special charges— 18 — — 18Special charges10 — 2 4 16Non-cash charges used— (18) (2) — (20)Cash payments(32) — — (3) (35)Foreign exchange rate impact(1) — — — (1)Balance at March 30, 2013$35 $— $—$9 $442011 Restructuring PlanDuring 2011, the Company announced a restructuring plan to streamline certain activities in the Company's legacy cardiac rhythm management business and sales and selling support organizations.

During 2011, the Company incurred charges totaling $162 million related to the 2011 restructuring plan.
